Application July 12, 1937, Serial No. 153,161

12 Claims.

The main objects of this invention are:

First, to provide a novel and improved means for securing a door latch handle, window elevating handle, or other handle or lever to a shaft or spindle associated therewith.

Second, to provide a structureof the type described wherein a handle may be quickly and readily assembled with its spindle or shaft and at the same time is effectively secured.

Third, to provide a structure of the type described wherein the securing means is entirel concealed,

Objects relating to details and economies of the invention will appear from the description to 15 follow. The invention is defined in the claims.

A structure embodying the features of the in-. vention is illustrated in the accompanying drawing, in which:

Fig. 1 is a view partially in section illustrating 20 the improvements as applied to a door, the means operated from the spindle not being illustrated.

Fig. 2 is a fragmentary view partially in section of the handle and the cooperating spindle in disassembled relation.

Fig. 3 is a perspective view of the spindle.

The invention primarily relates to the assembling of door operating or window elevating or the like handles with their spindles or shafts, being particularly concerned with the hardware of this type such as is commonly used on automobile doors and windows. It will be understood, however, that the scope of the invention is not limited in this respect and the provisions thereof may be adapted to a variety of fields or uses.

Referring to the accompanying drawing, the reference numeral I indicates a handle designed for operating a window and 2 its spindle. The spindle is associated with a suitable operating mechanism designated generally by the numeral 20. r

The handle is provided with an escutcheon 3 secured to a door panel or the like 4. The handle is provided with a socket or recess 5 designed to receive the squared or otherwise non-circular end 6 of the spindle 2. The cross section of the socket is such as to slidably receive the spindle and being conformed to its non-circular cross section, relative rotative movement of the two parts is prevented.

The recess has a small bore 1 at its inner end and in this recess I drive a suitable pin or screw 8, the threads 9 of which are preferably of relatively high pitch so that the threaded pin may be driven into the socket and cuts its own threads.

{55 If preferred, the pin may be positioned in the bottom of the socket by a casting with the handle thereon, the handles being commonly formed of die castings. The pin has hardened threads,- this result being commonly secured by casehardening. When the pins are driven into position in the 5 handle, the threads are substantially harder than the material of the handle. The pin is arranged so that a substantial portion thereof projects centrally into the socket. The pin is preferably tapered at its tip l0 to provide a pilot facilitating '10 its entry into the socket or bore ll of the spindle 2.

The spindle is provided with an insert l2 which .is arranged in the enlarged portion [3 of the bore of the spindle and secured therein by upsetting or swaging the end of the spindle thereon as shown at It, thus rotatably securing the insert or collar l2 in the spindle. This insert is in-effect a nut blank and becomes a nut when the parts are assembled as will-be hereinafter pointed out. In assembling, the spindle is commonly mounted in the door or other part with which it is associated and in operative relation to the part which it is designed to operate.

The handle may at any stage in the manufac- '25 ture of an automobile, for example, and after the upholstery indicated at l5 has been applied, be engaged with the spindle merely by slipping it upon the end of the spindle and driving it thereon. The pin engages the insert 12 and cuts or threads its way-into the same, the insert or collar rotating during this driving operation. When driven into place, the handle resistsall ordinary strains or stresses to which it is subjected and is effectively retained. It may, however, be removed by a slow sufficiently strong pull without in any wise injuring the parts and without preventing its being replaced. It is the usual practice to secure handles of this kind bymeans of pins or set screws and these usually require accurate positioning of the handle relative to the spindle in order to bring the pin or key holes into register. 1

While I have illustrated and described my improvements as embodied in a door or window opcrating handle, they may be readily embodied in valve handles and in many other relations. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patient, is:

1. In combination, a spindle having a portion of non-circular section, a member having a recess corresponding in section to the non-circular section of the spindle and adapted to receive the same, and means for securing the spindle and member in assembled relation comprising an anchoring screw having relatively high pitched, hardened threads thereon, the recess in said member being counterbored and saidscrew being driven into the counterbore to thread itself substantially therein, said spindle having an axial recess, a cylindrical insert mounted adjacent the; mouth of said spindle recess, said spindle being driven into the recess of said member with'the screw engaging and threading itself into the insert during the driving operation, said insert rm,

tating to permit said threading action, and means for retaining said insert in place adjacent said" mouth. v

2. In combination, a spindle, a mem erhaving I a recess adapted to receive the spindle, means for securing the spindle and-'member in assembled relation comprising arr-anchoring screw'having relatively high pitched, hardenedthreads thereon, the recess in said member being counterbored and said screw being driven into the counterbore to thread itself substantially therein, said spindle having anaxial -'-recess; acylindrical insert mounted adjacent the mouth of saidspindle re-' drical insert mounted adjacent the mouth of said spindle recess, said spindle being driven upon said screw with the screw engaging: andi 'thr'eading itself into the insert during the driving operation,.said insert rotating to permit said threading action, and meansforretaining: said insert in place adjacent said mouth. 3:

. 4. Means for securing a. handleito a spindle adapted to be rotated-thereby comprising a hardened screw threaded element,.=said :handle; and spindle having recesses adapted to," receive said element, said element being driven into the respective recesses, and means adjacentthe mouth of one of said recesses for absorbingrotation incident-to the threading action'of said element during the driving operation of -assembling'the handle and spindle as specified.

' 5..Means for securing .a handle to a member adapted to. be actuated thereby comprising an element having hardened projections. thereon,
